Signs and Symptoms of P0081 Code in Nissan Vehicles
The P0081 code is a common issue that Nissan vehicles may encounter. It indicates a problem with the intake valve control solenoid circuit in bank 2. This code can cause several symptoms that can affect the performance of your vehicle. Here are some of the signs and symptoms of the P0081 code in Nissan vehicles:
- Check Engine Light: The most common symptom of the P0081 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine that needs to be addressed.
- Reduced Engine Power: Another symptom of the P0081 code is reduced engine power. You may notice that your vehicle is not accelerating as quickly as it used to or that it is struggling to maintain speed.
- Engine Misfires: The P0081 code can also cause engine misfires. This means that one or more cylinders in your engine are not firing correctly, which can cause a rough idle or a loss of power.
- Poor Fuel Economy: If your vehicle is experiencing the P0081 code, you may notice that your fuel economy has decreased. This is because the engine is not running efficiently, which can cause it to use more fuel than necessary.
- Stalling: In some cases, the P0081 code can cause your vehicle to stall. This can happen when you are idling or when you are driving at low speeds.
If you notice any of these symptoms in your Nissan vehicle, it is important to have it checked by a professional mechanic. Ignoring the P0081 code can cause further damage to your engine and can lead to more expensive repairs in the future.
Possible Causes of P0081 Code in Nissan
The P0081 code in Nissan indicates a problem with the intake valve control solenoid circuit in bank 2. This code is usually triggered when the Engine Control Module (ECM) detects a fault in the solenoid circuit. Here are some of the possible causes of the P0081 code:
- Faulty Intake Valve Control Solenoid: The most common cause of the P0081 code is a faulty intake valve control solenoid. The solenoid may be stuck open or closed, or it may have an electrical problem that prevents it from functioning properly.
- Wiring Issues: The wiring that connects the intake valve control solenoid to the ECM may be damaged or corroded. This can cause a loss of signal or a short circuit, which triggers the P0081 code.
- ECM Malfunction: In some cases, the P0081 code may be triggered by a malfunctioning ECM. This is rare, but it can happen if the ECM is unable to properly communicate with the intake valve control solenoid.
- Low Engine Oil Pressure: The intake valve control solenoid relies on proper engine oil pressure to function. If the engine oil pressure is too low, the solenoid may not be able to operate correctly, triggering the P0081 code.
- Failed Variable Valve Timing (VVT) System: The VVT system is responsible for controlling the timing of the intake and exhaust valves. If the VVT system fails, it can cause the intake valve control solenoid to malfunction, triggering the P0081 code.
If you are experiencing the P0081 code in your Nissan, it is important to have it diagnosed and repaired as soon as possible. Ignoring the problem can lead to further damage to your engine and other components, resulting in more expensive repairs down the line.

Fixes for P0081 Code Nissan
The P0081 code in Nissan vehicles indicates a problem with the intake valve control solenoid circuit in bank 2. This can cause a variety of issues, including reduced engine performance, poor fuel economy, and increased emissions. Fortunately, there are several fixes that can address this problem.
1. Replace the Intake Valve Control Solenoid
The most common fix for the P0081 code is to replace the intake valve control solenoid. This component is responsible for controlling the flow of oil to the variable valve timing system, which can affect engine performance. A faulty solenoid can cause the system to malfunction, leading to the P0081 code.
2. Check the Wiring and Connections
In some cases, the issue may be with the wiring or connections to the intake valve control solenoid. A damaged or corroded wire can prevent the solenoid from receiving the proper signal, leading to the P0081 code. Checking the wiring and connections and repairing any damage can resolve the issue.
3. Clean or Replace the Oil Control Valve Filter
The oil control valve filter is responsible for filtering the oil that flows to the variable valve timing system. Over time, this filter can become clogged with debris, preventing proper oil flow and causing the P0081 code. Cleaning or replacing the filter can resolve the issue.
4. Check the Oil Pressure
Low oil pressure can also cause the P0081 code to appear. Checking the oil pressure and ensuring it is within the manufacturer’s recommended range can help resolve the issue.
5. Replace the Engine Control Module (ECM)
In rare cases, the issue may be with the engine control module (ECM) itself. If all other fixes have been attempted and the P0081 code persists, replacing the ECM may be necessary.
In conclusion, the P0081 code in Nissan vehicles can be caused by a variety of issues related to the intake valve control solenoid circuit in bank 2. Replacing the solenoid, checking the wiring and connections, cleaning or replacing the oil control valve filter, checking the oil pressure, and replacing the ECM are all potential fixes for this issue.
